Emerson Ovation 1C31122G01 Digital Output Module

The Emerson Ovation 1C31122G01 is a hot‑swappable digital output module for Ovation DCS distributed control system. It receives control commands from the Ovation controller via back‑plane bus, converts digital instructions into field‑side discrete output signals to drive solenoid valves, relays and other field actuators.

This rack‑slot I/O module is equipped with optical isolation, channel self‑diagnosis and front‑panel LED status indicators. It must work with matching field termination assembly. It serves as critical aftermarket spare for maintenance, overhaul and retrofitting of thermal‑power‑plant and petrochemical DCS control cabinets.
